2-41 Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
The DRL system will make your high and low
-beam
headlamps come on at a reduced brightness in
daylight when:

The ignition is on with the engine running,

the headlamp switch is OFF,

the parking brake is released, and

the transaxle is not in PARK (P) on models with an
automatic transaxle only.
This indicator light on
your instrument panel
cluster will come on
when the DRL are on.A flashing DRL telltale indicates a possible burned out
headlamp, or that the vehicle may need service to repair
a stuck DRL relay.
When the DRL are on, your high and low
-beam
headlamps will be on at a reduced brightness. The
taillamps, sidemarker and other lamps won't be on.
Your instrument panel won't be lit up either.
When you turn on the headlamp switch, your high and
low
-beam headlamps will go out, and your low-beam
headlamps will come on. The other lamps that come
on with your headlamps will also come on.
When you turn off the headlamp switch, the regular
lamps will go off, and your high and low
-beam
headlamps will come on to the reduced brightness.
To idle your vehicle with the DRL off, set the parking
brake. The DRL will stay off until you release the
parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-71 Malfunction Indicator Lamp
(Check Engine Light)
United States Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The CHECK ENGINE light comes on
to indicate that there is a problem and service is
required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
NOTICE:
Modifications made to the engine, transaxle,
exhaust or fuel system of your vehicle or the
replacement of the original tires with other
than those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the CHECK ENGINE light to
come on. Modifications to these systems could
lead to costly repairs not covered by your
warranty. This may also result in a failure to pass
a required Emission Inspection/Maintenance test.

2-77 Fuel Gage
United States Canada
Your fuel gage tells you about how much fuel you
have left. When the indicator nears empty, the
CHECK GAGES light will come on. You still have
about 1.5 gallons (5.7 L) of fuel left, but you should
get more soon. See ªCheck Gages Lightº earlier in
this section for more information.Here are four things that some owners ask about.
None of these show a problem with your fuel gage:

At the service station, the gas pump shuts off
before the gage reads full.

It takes a little more or less fuel to fill up that the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took
a little more or less than half the tank's capacity to
fill the tank.

The gage moves a little when you turn a corner
or speed up.

The gage doesn't go back to empty when you
turn off the ignition.
For your fuel tank capacity, see ªCapacities and
Specificationsº in the Index.

RPT (6): Press this button once to hear a selection
over again. RPT will appear on the display. The current
selection will continue to repeat. RPT will flash on the
display while the cassette player is searching for the
start of the selection. Your tape must have at least three
seconds of silence between each selection for RPT to
work. Press this button again to turn off repeated play.
OFF will appear on the display.
AM
-FM: Press this button to play the radio when
a tape is in the player. The tape will stop but remain in
the player.
TAPE: With a cassette tape in the player and the radio
playing, press this button to play a cassette tape. CAS
will appear on the display. Press AM
-FM to return to the
radio when a cassette tape is playing. The inactive tape
will remain safely inside the radio for future listening.
In order to use a portable CD player adapter or a cassette
tape head cleaner you must disable the TIGHT/LOOSE
TAPE sensor. Press and hold the TAPE button for two
seconds with the radio off and the vehicle on. CAS will
flash on the display showing the TIGHT/LOOSE TAPE
sensor has been disabled. The feature will remain
disabled until the tape is ejected.
EJECT: Press the upward triangle button to
remove a tape. The radio will play. Eject may be
activated with the radio off. Cassette tapes may be
loaded with the radio and vehicle off if this button is
pressed first.
CLN: If this message appears on the display, the
cassette tape player needs to be cleaned. It will still play
tapes, but you should clean it as soon as possible to
prevent damage to the tapes and player. See ªCare of
Your Cassette Tape Playerº in the Index. After you
clean the player, press and hold the eject button for five
seconds to reset the CLN indicator. The radio display
will flash
--- to show the indicator was reset.
Radio Calibration
Your audio system has been calibrated for your vehicle
from the factory. If CAL appears on the display it means
that your radio has not been configured properly for
your vehicle and must be returned to the dealership
for service.

When using a scrubbing action, non-abrasive cleaning
cassette, it is normal for the cassette to eject because
your unit is equipped with a cut tape detection feature
and a cleaning cassette may appear as a broken tape.
To prevent the cleaning cassette from being ejected,
use the following steps.
If your vehicle is equipped with the AM
-FM Stereo with
Cassette Tape Player:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.
3. Press and hold the TAPE button for five seconds.
CAS will flash on the display for five seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
If your vehicle is equipped with the AM
-FM Stereo with
Cassette Tape and Compact Disc Player with Radio Data
System and Programmable Equalization:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.3. Press and hold the TAPE CD button for five seconds.
READY will appear on the display for five seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
When the cleaning cassette has been ejected, the cut tape
detection feature is active again.
You may also choose a non
-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head. This type of cleaning cassette will not
eject on its own. A non
-scrubbing action cleaner may
not clean as thoroughly as the scrubbing type cleaner.
The use of a non
-scrubbing action, dry-type cleaning
cassette is not recommended.
After you clean the player, press and hold the cassette
eject symbol or EJT button for five seconds to reset
the CLEAN or CLN indicator. The radio will display
CLEANED or
--- to show the indicator was reset.
Cassettes are subject to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before you have your tape
player serviced.

If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission
control label), it is designed to operate on fuels that meet
California specifications. If such fuels are not available
in states adopting California emissions standards, your
vehicle will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on your
instrument panel may turn on and/or your vehicle may
fail a smog
-check test. (See ªMalfunction Indicator
Lampº in the Index.) If this occurs, return to your
authorized Chevrolet dealer for diagnosis to determine
the cause of failure. In the event it is determined that the
cause of the condition is the type of fuels used, repairs
may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane
-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask your service station operator whether or
not the fuel contains MMT. General Motors does not
recommend the use of such gasolines. If fuels containing
MMT are used, spark plug life may be reduced and your
emission control system performance may be affected.
The malfunction indicator lamp on your instrument
panel may turn on. If this occurs, return to your
authorized Chevrolet dealer for service.To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and
fuel system, allowing your emission control system
to function properly. Therefore, you should not
have to add anything to the fuel. In addition, gasolines
containing oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
contribute to clean air. General Motors recommends that
you use these gasolines, particularly if they comply with
the specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don't use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn't
be covered under your warranty.

6-31 Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built
-in wear indicators that make
a high
-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come
and go or be heard all the time your vehicle is moving
(except when you are pushing on the brake pedal firmly).
CAUTION:
The brake wear warning sound means that soon
your brakes won't work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a
brake squeal when the brakes are first applied or
lightly applied. This does not mean something is
wrong with your brakes.
See ªCaliper/Knuckle Maintenance Inspectionº in
Section 7 of this manual under Part C ªPeriodic
Maintenance Inspections.º
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel nuts in the
proper sequence to GM specifications.
Your rear drum brakes don't have wear indicators,
but if you ever hear a rear brake rubbing noise, have the
rear brake linings inspected immediately. Also, the rear
brake drums should be removed and inspected each time
the tires are removed for rotation or changing. When
you have the front brake pads replaced, have the rear
brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
See ªBrake System Inspectionº in Section 7 of this
manual under Part C ªPeriodic Maintenance Inspections.º

6-44
When It's Time for New Tires
One way to tell when it's
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only 1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire if any of the following statements
are true:

You can see the indicators at three or more places
around the tire.

You can see cord or fabric showing through the
tire's rubber.

The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
The tire has a bump, bulge or split.

The tire has a puncture, cut or other damage that
can't be repaired well because of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need,
look at the Tire
-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire's sidewall. When you get new tires,
get ones with that same TPC Spec number. That way
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service
on your vehicle. If your tires have an all
-season tread
design, the TPC number will be followed by an ªMSº
(for mud and snow).
If you ever replace your tires with those not having
a TPC Spec number, make sure they are the same
size, load range, speed rating and construction type
(bias, bias
-belted or radial) as your original tires.
